SEEDING DEVICE.

SPECIFICATXON forming part of Letters Patent No. 719,905, dated February3, 1903.

Application led June 2,1902. Serial No. 109,998. (No model.)

To n/ZZ whom t may concern:

Be it known that I, JACOB TCHooLJIAN, a citizen of the United States,residing at Del Rey, in the county ofFresno and State of California,have invented new j and useful Improvements in Seeding Devices, of whichthe following is a specification.y

My invention relates to improvements in devices for seeding ground afterit has been plowed, and the primary object thereof is to provide aremovable seeding attachment of novel construction for gang-plows.

A further object of my invention is topprovide suitable mechanismwhereby the seeder can be operated through power derived from the plow.

Other objects and advantages of the invention will be fully understoodfrom the following description and claims when taken in conjunction withthe accompanying drawings, in whichj Figure 1 is a view in sideelevation of a gang-plow provided with my improvement. Fig. 2 is a rearview of my improved seeder attachment removed from the plow. Fig. 3 is aview in side elevation of the rear portion of a gang-plow provided withthe present invention and embodying a slight modification. Fig. .tis avertical longitudinal section of one of the feed-tubes and hopper. Figs.5, 6, and 7 are detail views of the feed-slides. Fig. 8 is -an enlargedView of the lower end of one of the feed-tubes constructed in accordancewith the present invention.

Referring to the drawings by numerals of reference, 1 indicates the mainframe of a gang-plow, and 2 indicates one of the bearing-wheels, all ofwhich may be of any suitable construction.

Arranged upon the rear portion of the frame 1 is the seed-hopper 3,which is preferably detachably secured to said frame in any'suitablemanner. In its rear side the seed-hopper is provided with a series ofopenings et, which openings permit the seed to pass from the hopper intothe short depending spouts 5 and be discharged therefrom through theseed-tubes 6 upon the ground. Depending from the opposite ends of theseed-hopper are the approximately V-shaped arms 7, which are connectedat the angles of intersection and lower ends by transverse bars 8 and 9.

i connect the upper ends of the'feed-tubes with the spouts 5. By thisconstruction it will be perceived that in the event of the feed-tubesstriking an obstruction they will work on their pivots and the lowerends will be swung backward temporarily until they pass and then bereturned to their normal positions by the springs 12. The springs 12 areconnected to the transverse bar 9 and have their outer ends connected tothe lower portions of the seed-tubes 6.

13 designates vertically-movable feed-slides arranged on the inner faceof the rear side of the seed-hopper, each slide being provided with aninclined feed-opening adapted to rebister with the adjacent openings 4.in the hopper. In order to support the feed-slides in their relativepositions and prevent displacement thereof, I provide openings in thebottom of the seed-hopper to receive the lower ends of the feed-slides13 and support their upper ends in brackets 14.

From the foregoing description it will be understood that as thefeed-slides are reciprocated the seed willbe permitted to pass throughthe inclined openings of the feedslides into the seed-tubes and thusdeposited upon the ground.

, Extending outward and upward from the upper forward corner of theseed-hopper are the angular brackets 15, the upper ends of which areprovided with bearings to receive the transverse rock-shaft 16, which isprovided at one end with a crank-arm 17. Secured to the shaft 16 andextending rearward therefrom are the short arms 18, which arms areadapted to be received in eyes 19, secured to the upper ends of thefeed-slides.

2O designates a sprocket-wheel secured to the bearing-wheel 2 of thegang-plow and around which passes a chain 21, through the medium ofwhich power is transmitted to a smaller sprocket-wheel 22, journaled ona bearing secured to the seed hopper and around which the'chain 21 alsopasses.

In order to impart the necessary movement to the shaft 16 and therebyreciprocate the feed-slides, l mount a link 23 eccentrically` on IOO thesprocket-wheel 22 and connect its other end to the crank-arm 17, asclearly shown in Fig. 1.

The lower portions of the feed-slides are channeled, as at 24C, toreceive adjusting-slides 25, which have their upper edges inclined toregister with the inclined openings in the feedslides. The slides 25 aredesigned to serve as feed-regulators and are held in their adjustedpositions by set-screws 26, which extend through elongated slots 27,formed in the feedslides.

28 designates the depending tubes, the rear ends of which extendrearward of the said tubes in parallel planes and are provided withbearings to receive the short shafts upon which the seed-scatterers 29are secured. The seed-scatterers 29 each comprises an elongated bodyportion, the lower portion of which is bent forward at right anglesthereto, as at 30, and it will be readily seen that as they swing ontheir pivots seed falling from the seedtubes will strike the scatter-ersand be thoroughly scattered and spread over the surface of the ground.

In Fig. 3 I have shown a slight modification of the preferred means foroperating the crank-shaft 16,by which construction the endless chain 21and the link 23 are eliminated and a direct connection between thesprocketwheel 2O and the crank-arm 17 is effected. In this constructionI employ a pitman 31, which has its lower end eccentrically mounted onthe sprocket-wheel 2OV and its upper end journaled on the lower end ot'the crankarm 17.

All the parts being assembled, the operation of the device is asfollows: As the gang of plows is moved forward power is transmittedthrough the endless chain 21 to the sprocket-wheel 22, which,through themedium of the ecoentrically-mounted link 23, oseillates the rock-shaft16, and thereby imparts the necessary reciprocating movement to thefeed-slides.

I-Iaving thus described the invention, what is claimed as new is- 1. Ina device of the class set forth, the combination with a plow frame, of abearingwheel connected to and supporting the said frame, a seed-hopperarranged on the frame and provided with seed-outlets, verticallydisposedreciprocable slides in the hopper adjacent to and cooperating with saidoutlets, a series of depending tubes connected to the outlets of thehopper and pivotally supported to have a rearward movement, means forreturning the tubes to normal position, shoes on the lower ends of thetubes, and seed-scatterers movably attached to and depending from therear portion of the shoes.

2. In a device of the class set forth, the combination with a plow-framehaving a seedhopper thereon,of a series of depending tubes connected tothe seed-hopper and provided with shoes at their lower ends, anddepending seed-scatterers pivotally connected to the rear portions ofthe said shoes.

3. A seeder attachment comprising a seedhopper provided withseed-openings in one of its walls and having openings in its bottombeneath the said seed-openings, feed-slides arranged adjacent the saidseed-openings and having their lower ends projecting through theopenings in the bottom of the seed-hopper, means for supporting theupper portions of the feed-slides, brackets secured to the upper sidesof the opposite ends of the hopper and formed with bearings, arock-shaft journaled in said bea-rings, aconnection between the saidslides and rock shaft, depending arms secured to the opposite lower endsof the seed-hopper, a transverse bar connecting the said arms,seed-tubes pivotally connected to said transverse bar, a exibleconnection between the upper ends of the seed-tubes and the seed-openings in the hopper, and means for oscillating the said rock-shaft.

4. A seeder comprising a hopper, a Series of feed-slides arranged Withinthe hopper, means for operating the feed-slides simultaneously,depending arms secured to the opposite ends of the hopper, a transversebar connecting the said depending arms, seedtubes pivotally connected tosaid transverse bar, depending spouts secured to the seedhopper abovethe seed-tubes, a flexible coupling between the said spouts andseed-tubes, and a resilient connection between the lower ends of thesaid shoes and depending arms.

5. In a device of the character described, the combination with aplow-frame; of a bearing-wheel connected to and supporting the Amainframe, a seed-hopper arranged on the main frame and having seed-openingsin one of its walls, vertically-movable feed-slides arranged adjacentthe said seed-openings, eyes secured to the upper ends of thefeed-slides, brackets secured to the opposite ends of the hopper andformed with bearings, a rockshaft j ournaled in said bearings, acrank-arm on one end of said rock-shaft, a series of arms secured to andprojecting outwardly from the said rock-shaft and having their outerends projecting through the eyes of the feed-slides, and means wherebypower is transmitted from the traveling wheel to the said crank-arm.

In testimony whereof I afx my signature in presence of two witnesses.
